What Is In A Dormant Spray Kit?

A Dormant Spray Kit combines lime-sulphur and horticultural oil, and it can be used on trees (including fruit trees), shrubs (including roses), and other deciduous ornamentals.

 

How Does Dormant Spray Work? What Does It Do?

When applied in the fall, the Dormant Kit is a great for controlling pests that overwinter on trees and plants.

The horticultural oil in the kit will smother aphid eggs and control scale (including Oystershell scale and Scurfy scale). At the same time, the lime-sulphur in the kit will control overwintering fungal disease.

 

When applied in the spring, the horticultural oil will smother active pests such as aphids, caterpillar eggs, leafhoppers, mealybug, mites, scale, spider mites, thrips, and whiteflies are the most common targets of horticultural oil.

The Lime Sulphur specifically targets fungi. And controls black knot, leaf spots, powdery mildew and different blights.

 

When Should the Dormant Kit Be Applied?

Apply in early spring just before either leaves or flowers show signs of swelling, breaking open or when buds show green at tips. You don’t want to apply too early though, since the insects need to be active and breathing, in order to be affected. Spray on a day when temperature is mild (over 5 C). Apply early in the day to allow sufficient time for the dormant spray to dry on the tree before there is a chance of freezing.

In the fall, dormant spray can be sprayed when the leaves of the plant have died or fallen off but when the temperature is still above 5°C.

 

Are there plants that can be injured with dormant spray?

Yes. Always read the entire label and look for information regarding the susceptibility of various plant species and varieties to injury from dormant spray applications.
